APNS-162 - Fallen Student Council President M's Mark, Sakura Remu

At a prestigious school, Remu lived each day as an excellent student, a model for other students. One day, she was called to school on a holiday by her teacher, Hirai. It was under the guise of make-up lessons, but Hirai, along with the former principal Nakada, overpowered Remu. From that day on, she was called to Hirai's classroom during lessons for fellatio, and other teachers joined in for group sex... Finally, she was thrown into a group of students attending evening classes and subjected to thorough masochistic education.
